Abstract

Background: As you get older, some cells in the body experience a decrease in the amount of production, including hyaluronic acid. Hyaluronan or hyaluronic acid (HA) is a molecule involved in skin moisture. Skin that loses moisture easily becomes dehydrated and signs of aging appear. Moreover, extrinsic factors such as exposure to UV rays and changing weather conditions also affect the condition of the skin and cause damage to the skin's protective layer. Objective: to determine the role and effectiveness of hyaluronic acid for skin rejuvenation. Methods: Literature review with the title “The Role of Hyaluronic Acid for Skin Rejuvenation” is gain by systematic reviewing of some original research article journal and literature review using search engines such as Google Scholar, PubMed, Scopus, and Elsevier. Results: Hyaluronic Acid (HA) has a role in regulating various biological processes such as skin repair, wound healing, anti-inflammatory, tissue regeneration, and immunomodulation. HA filler injection is an effective therapy for skin rejuvenation because it hydrates, removes fine lines and signs of aging on the skin, and is used to shape facial anatomy according to the patient's wishes. Conclusion : Hyaluronic acid is proven to have effectiveness on skin rejuvenation.

Abstract

The Putri Cempo landfill serves as the final disposal site for organic and inorganic waste. Waste from the landfill can dissolve and settle in river sediments, potentially accumulating heavy metals, such as iron (Fe) and manganese (Mn), which easily bind to organic matter. This study aims to determine the content of Iron (Fe) and Manganese (Mn) in rivers around the Putri Cempo landfill. The concentrations of Fe and Mn weres analyzed using atomic absorption spectrometry (AAS) according to SNI 6989.84:2019, with sediment sampling conducted in rivers around the Putri Cempo landfill. Sediment sampling in these rivers revealed Fe levels of 1519.414245 mg/L and Mn levels of 130.033 mg/L. The analysis indicated that Fe concentrations exceeded the established quality threshold, whereas Mn levels remained below it. Heavy metals like Fe and Mn negatively impact abiotic and biotic environments, including human health and agricultural productivity. Elevated heavy metal levels disrupt ecosystem balance and pose health risks, making their management crucial. Reducing heavy metals in river sediments near the landfill is essential. Remediation efforts using bioremediation and phytoremediation technologies can help mitigate these impacts. Ongoing efforts are necessary to control heavy metal contamination in river sediments, ensuring ecosystem stability and public health.

Abstract

Wastewater from metal plating businesses contains hazardous heavy metals, including chromium (Cr), which must be properly treated to avoid environmental contamination. Adsorption utilizing natural materials, such as sugarcane bagasse, is a promising option. This study compared the effectiveness of H2SO4-activated sugarcane bagasse with sugarcane bagasse-based activated carbon in removing total chromium (Cr-T) from metal plating wastewater and analyzed the effects of adsorbent mass and contact time. Atomic absorption spectrophotometry (AAS) was used to measure the final chromium concentrations after batch adsorption was conducted with different masses and contact periods. The findings revealed that the adsorption effectiveness increased as the adsorbent mass and contact duration increased, reaching an ideal point. While activated carbon achieved its peak at 12 g and 120 min (95% and 47.6% efficacy, respectively), activated bagasse performed best at 15 g and 150 min (51.9% and 43% effectiveness, respectively). Activated carbon performed better because of its increased surface area and pore structure resulting from carbonization. These results demonstrate that sugarcane bagasse is a potential, affordable, and sustainable natural adsorbent for lowering total chromium in industrial effluents, particularly when transformed into activated carbon.
